How Much Product Do You Really Need?

Blowing through your beauty products like Rihanna blows through hairstyles? Your serving sizes may be way, way off

If a little bit is good, then a lot must be better, right? Not when it comes to your beauty products. According to experts, the products we use on a daily basis adhere to the Goldilocks principle. Too small of a dollop may mean your anti-aging serum may not work at all, but too big of a blob of deep conditioner could mean greasy hair and split ends (not to mention a depleted bank account).

Here, skin care expert Annet King, director of global education at Dermalogica and hairstylist Arturo Swayze for Arturo Salon and René Furterer show us just how much product you should be applying to make sure it's working -- but not sabotaging your beauty routine.
